.DOMESTIC SINK.

SPECIFICATION forming part of Letters Patent No. 786,738, dated April 4, 1905.

i Application filed September 22, 1904. Serial No. 225.466.

1'0 @M yzzz/tom it may concern:

Be it known that I, JOHN H ENRY DOYLn, a citizen of the United States, and a resident of New Orleans, in the parish of Orleans and State of Louisiana, h-ave invented a new and Improved Domestic Sink, of which the following is a full, clear, and exact description.

My invention relates to domestic sinks, ba-

sins, and the-like, my more particular object being to provide means for iiushing the drainpipe without the necessity of passing water through the sink, basin, or analogous utensil.

`My invention further relatesl to certain improvements in the construction of domestic sinks and the like, substantially as described below and defined in the appended claims. Reference is to' be had lto the accompanying drawings, forming a part of this specification, in which similar characters of reference indi cate corresponding parts in all the figures.

Figure 1 is a frontelevation, partly in section, on the line 1 1 of Fig. 2,' showing one form of my device as appliedto a sink or analogous domestic utensil. tical section through the same upon the line 2 2 of Fig. 1 looking in thev direction of the arrow. Fig. 2ais a Jfragmentary section upon the line 2iL 2 of Fig. 2 looking in the direction of the arrow and showing means for producing a spiral spray within the funnel of the device. Fig. 3 is afragmen'tary section somewhat similar to Fig. 2 and on the line 3 3 of Fig. 4, but showing another form of mechanism for producingthe whirling jet; and Fig. 4 is ahorizontal section upon the line 4 4 of Fig. 3 looking in the directionof the arrow and showing the pipe for producing a whirling spray and also indicating how the pipe is placed in position.

A receptacle 5, such as a sink or basin, is provided at its bottom with a funnel 6, having a liange 6 integral therewith, this flange being provided with screws 7 orfother fastenings whereby the funnel is held in position l perforations 10, is covered by a screen'll,

made, preferably,concave and perforated, as

Fig. 2 is a ver-` shown. A casing 12, preferably integral with the body portion of thesink or basin, is providedv with a chamber 13, through which .passes a pipe 14, provided at'its upper end l2u the globe-valve 20 is in communication with an annulus 14, integral with the body portion 5 of the sink or basin, this annulus being provided witha passage 14, cored through the solid metal and bent laterally, as indicated in Fig.y 2*. This cored passage 14b admits the water to the funnel 6 in the form of awhirling jet, the admission of the water being controllable by a hand-valve 21.

The construction shown in Figs. 3 and 4'differs from that shown tin the other figures in having the casing 12, provided withthe chamber 13, made comparatively large,as indicated, and in having a pipe 14, provided with a spout 14, bent laterally, as indicated, the position of this pipe being such that it directs a jet of water laterally. so as to strike the funnel 6 at an angle, thus producing a whirling jet. The

chamber 13 is given the shape indicated in- Fig. 4 in' order to allow for the introduction of the pipe 14d and to permit the same to be adjusted before being firmly secured in position.` The manner of introducing this pipe is indicated by dotted lines in Fig. 4. The pipe being once in position and firmly secured is no longer movable.

It will be noted that in both forms above de? IOO Having thus described my invention, claim as new and desire to secure by Letters Patentl. The combination oabasin provided at its bottom with an aperture, a pocket connected with said basin and projecting through said aperture, said pocket being` provided with perforations, and means for directing' a stream of Water tangentially against the exterior of said pocket.

2. The combination of a basin provided with a perforated pocket depending therefrom, and means for directing` a stream of Water tangeir' tiaily upon the outer surface of said pocket.

3. The combination of a basin provided with a perforated pocketdependng therefrom, andl also provided with a screen covering said pocket, and means for directing` a stream of water tangentially against the exterior of said pocket.

e. The combination of a basin provided with 2O JOHN HENRY DOYLE,
